Objective:
To study the expression and prognosis of DHX32 in pancreatic cancer and observe the biological function of DHX32 in pancreatic cancer cell line SW1990 . To investigate the clinical significance and prognostic value of DHX32 in pancreatic cancer , and predict the possible related mechanism.
Methods :
GEPIA database was used to analyze the expression and prognosis of DHX32 in pancreatic cancer , and TCGA database was used to analyze the relationship between DHX32 mRNA expression level and clinicopathological features and prognosis of patients with pancreatic cancer. The effects of DHX32 on the proliferation , invasion and migration of SW1990 pancreatic cancer cells were studied by EdU immunofluorescence assay , Transwell assay and scratch assay. GSEA was used to predict DHX32 the possible related signaling pathways involved with DHX32 in pancreatic cancer.
Results:
The results of GEPIA database analysis showed that the expression level of DHX32 in pancreatic cancer tumor tissues was significantly higher than that in normal pancreatic tissues ( P < 0. 05 ) . Meanwhile , the prognosis of pancreatic cancer patients with high DHX32 expression was worse than that of patients with low DHX32 expression (P < 0. 001) . Cox regression analysis showed that DHX32 mRNA expression level and M stage were independent risk factors for prognosis of pancreatic cancer patients (all P < 0. 05) . EdU immunofluorescence assay , Transwell assay and scratch assay confirmed that the overexpression of DHX32 promoted the proliferation , invasion and migration of pancreatic cancer cells (all P < 0. 001) , while silencing DHX32 inhibited the proliferation , invasion and migration of pancreatic cancer cells ( all P < 0. 001) . The results of GSEA enrichment analysis showed that DHX32 was enriched in four signaling pathways : hematopoietic cell lineage , neuroactive ligand receptor interaction , primary immune deficiency and spliceosome (all P < 0. 05) .
Conclusion
DHX32 is highly expressed in pancreatic cancer. It promotes the proliferation , invasion and metastasis of pancreatic cancer cells , and is closely related to the poor prognosis of pancreatic cancer patients .

Journal of Modern Laboratory Medicine 2025;40(1):138-142
Objective To exploring the correlation between serum periostin,uric acid/albumen ratio(UAR) levels and recurrence after radiofrequency ablation (RFCA) in elderly patients with nonvalvular atrial fibrillation (NVAF). Methods The 108 elderly NAVF patients who received RFCA treatment at the Cardiovascular Center of Peking Tongren Hospital Affiliated to Capital Medical University from January 2019 to October 2022 were selected as the observation group,selected 108 healthy individuals who had medical checkups at Beijing Tongren Hospital Affiliated to Capital Medical University during the same period as the control group,and the patients were followed up for a period of 1 year. And according to the follow-up,they were divided into the recurrence group (n=42) and the non-recurrence group (n=66). Sex,age,body mass index (BMI),history of hypertension,diabetes mellitus,hyperlipidemia,smoking,alcohol consumption,left ventricular ejection fraction (LVEF),left ventricular end-diastolic diameter (LVEDD),white blood cell counts were collected. Enzyme linked immunosorbent assay (ELISA) was applied to detect serum Periostin level. Fully automated biochemical analyzer was applied to measure the levels of serum albumin (ALB) and uric acid (UA),whose ratio was the level of UAR. Logistic regression was applied to analyze the influencing factors of recurrence in NVAF patients after RFCA. Receiver Operating Characteristic (ROC) curve was applied to analyze the predictive value of serum Periostin and UAR levels for recurrence after RFCA in elderly NAVF patients. Results Preoperative Periostin,UAR levels in the observation group were significantly higher than serum Periostin (53.53±6.27ng/L),UAR (4.09±0.78) in the postoperative(50.53±7.23 ng/L,3.41±0.91)and control groups(31.29±4.21 ng/L,1.24±0.27),and the differences were statistically significant (t=3.258,30.603;5.896,35.883,all P<0.05). The LVEF was lower in the recurrent group (51.16%±6.49%) than in the non-recurrent group (55.39%±6.71%),the levels of UAR (4.01±0.92),Periostin (55.77±6.56 ng/L) and percentage of history of hyperlipidemia (66.67%) were higher in the relapse group than those in the non-relapse group (3.02±0.63,47.19±5.44 ng/L,34.85%),and the differences were statistically significant (x2/t=3.234,6.458,7.180,10.426,all P<0.05). Serum Periostin[OR(95% CI):1.856(1.148~3.000)]and UAR[OR(95% CI):2.127(1.145~3.951)]were independent risk factors for recurrence after RFCA in patients (P<0.05). The area under the curve (95% confidence interval)[AUC(95%CI)]of serum Periostin and UAR levels to predict relapse after RFCA in elderly NAVF patients were 0.856(0.776~0.916),0.817(0.731~0.884),respectively,the cutoff values were 53.00 ng/L,3.99,the Youden index was 0.569,0.509,the sensitivity was 88.10%,85.71% and the specificity was 71.21%,65.15%,respectively. The combined predicted of the AUC(95%CI),Youdon index,sensitivity and specificity by the two method were as flows 0.924 (0.857~0.966),0.736,85.71% and 87.88%,respectively. The combined prediction was significantly higher than that of each index alone (Z=2.296,2.880,P=0.022,0.004). Conclusion Serum Periostin and UAR levels are upregulated in elderly patients with NAVF,there is a certain correlation with recurrence after RFCA,the combination of the two has a high efficacy in predicting recurrence in elderly NAVF patients after RFCA.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T NANC), time to symptom improvement (T SI), and time of hospital stay (T HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

OBJECTIVE To optimize the forming process of Yindan huoxue tongyu granules, and evaluate the quality of the granules. METHODS Taking forming rate, angle of repose, moisture, moisture absorption rate and dissolution rate as indexes, single factor experiment combined with Plackett-Burman design was adopted to screen key process parameters; analytic hierarchy process combined with entropy weight method and Box-Behnken response surface method were used to optimize the molding process of Yindan huoxue tongyu granules, and the forming process was verified. The relative homogeneity index, bulk density, vibration density, Hausner ratio, angle of repose, moisture and hygroscopicity were used as secondary physical indexes to establish the physical fingerprints of 10 batches of Yindan huoxue tongyu granules to evaluate particle quality consistency. RESULTS The optimal molding process of Yindan huoxue tongyu granules was as follows: mannitol as the fixed excipient, the drug-assisted ratio was 1∶1(m/m) and the drying time was 1 h; 90% ethanol was used as wetting agent and the amount of it was 32%, the drying temperature was 70 ℃. The results of validation tests showed that the average comprehensive score was 97.45, which was close to the predicted value of 97.18. The similarities between the physical fingerprints of 10 batches of Yindan huoxue tongyu granules prepared by the optimal molding process and the reference physical fingerprint were all higher than 0.99. CONCLUSIONS The molding process is stable and feasible, and the quality of Yindan huoxue tongyu granules produced is stable and controllable.
